I purchased a D4 (2011) about 3 months ago - had no issuse since. I go to Austria on Thursday for 6 months... Hence my urgent need

I enabled timed climate a few months ago with the IID tool but never got it working from inside the cabin. - didnt think anything of it as when I tested it on the IID tool, i had to press it a few times but it would usually come on for a few minutes and successfully test etc and I was planning on buying an Altox.

Bought an Altox and installed it yesterday, pretty certain its installed correctly, but I couldnt get it working. Put the IID tool on it now and got 3 errors:-

Lost comms with auxillary control module
open circuit and brake control module.

I reset them and tried again but kept getting code Operation Failed A7. The fuel primed ok just before testing.

Is there anyone in the Leeds area who can have a look at this please - I got to Austria Thursday early am so not got long.
